The performance of advance photocatalytic degradation of 4-chlorophenol (4-CP) strongly depends on photocatalyst dosage, initial concentration and time of reaction. The aim of this study was modeling and investigating the degradation of it in water using TiO2/Fe as a nanocatalyst.
Photocatalyst was optimized by varying and operating parameters and using a response surface methodology to evaluate the experimental data. Based on the results obtained, it was found that a maximum of 91% of 4-CP was successfully degraded under optimal conditions (2.29 g catalyst dosage, 38.5 mg/L of 4-CP and time 236.85). All the experimental data showed good agreement with the predicted results obtained from statistical analysis.
